LAMP-CORD ADJUSTER AND THE LIKE.

T 0 all whom if may concern Be it known that I, JOSEPH SACI-rs, acitizen of the United States, and resident of Hartford, in the county ofI-Iartfo-rd and State of Connecticut7 have invented certain new anduseful Improvements in Lamp- Cord Adjusters and the Like, of which thefol-p lowing is a specification.

rI he object of the invention is to produce al device of the classspecified having features of novelty and advantage.

In the drawings Figure l is a side elevation of the complete device.Fig. 2 is an edge view thereof. Fig. 3 is a central vertical section ofthe upper member. Fig. 4 is an inside view of one side thereof. Fig. 5is an inside view of the opposite side. Fig. 6 is a transverse sectionof the lower member. Fig. 7 is an inside view of one side thereof. Fig.8 is an inside view of the other side thereof. Fig. 9 is a perspectiveview of one of the weights.

I have shown my invention in connection with its use for the purpose ofadjusting the position of an incandescent lamp, although it is evidentthat the adjuster can be used for other purposes. The description willbe confined to the embodiment which has been selected for illustration.

In the drawings, a denotes the base of the rosette which is fastened tothe ceiling and b the removable cap to which the conductor c isconnected.

The adjuster comprises an upper member l and a lower member 20. Thecable c passes through a direct channel 2 in the upper member, thencethrough a return channel in the lower member formed by the pulley QQ,thence up and through a return channel in the ripper member formed bythe pulley Ll, thence down and through a direct channel 2l in the lowermember. The upper member is supported by the chains Z which are attachedto the ceiling in any desired way as by the hooks e-e whose ends slipunder the rosette, thus relieving the cable and rosettecap from thestrain of supporting the weight of the parts of the adjuster. The lowermemberA is weighted to meet the requirements of a given case, but alwaysin such a i manner that the light will stay where it is positioned.

In detail the ripper member l is formed of insulating material such asporcelain and is made in two parts 5 6, These two parts Speccaton ofLetters Patent.

are oppositely grooved as at 77 so that when fitted together they formthe direct channel 2 and preferably the cable is of such a size that itlits snugly in this channel, the channel being given a curved form so asto assist in the frictional attachment of the upper member to the cable.The section 6 is provided with a hub 8 upon which the pulley 4L ismounted. The two parts are secured together by a pin l0 under the headsof which lie the ends of the wire bands 11 to which the chains CZ areattached. In detail the lower member 2O is also made of insulatingmaterial and is formed in two parts 30-31, the part 31 having a hub 32on which the pulley 22 is mounted. Extending centrally across the innerface of the part 30 is a groove 84 forming, with the grooved top andbottom, projections 35-36 on the part 31 and the grooved end 37 of thehub 32. Recesses 38 are provided in one or both faces of the lowermember to receive weights 39 the number or size of which can be variedto increase or decrease the weight of the lower member as desired. rI`hetwo parts of the lower member are held together by the spring ring 40 orin any other desirable manner. To lower the light it is only necessaryto draw down on the end of the cable, which action, of course, draws theupper and lower members nearer together. To raise the light it is onlynecessary to lift up on the lower end of the cable when the weight ofthe lower member 2O will cause it to drop separating the upper and lowermembers and taking up the slack of the cable.

All parts of the upper member except the pin l0 and the wire bands 11may be made of insulating material and all parts of the lower member,except the spring ring which holds the two parts together, may be ofinsulating material. The chains CZ provide for supporting the completedevice independently of the cable and rosette, thus removing any dangerof the rosette cap being pulled out during the ordinary use of theapparatus.

It is to be particularly noted that by the herein described constructionand arrangement of parts the upper and lower ends of the cable are insubstantial alinement affording a symmetrical arrangement and obviatingany possibility of the various twisted together due to the sectionalconstruction.

The device can be applied to an existing installation by merelypositioning the cable properly in the channels and clamping the partstogether.

am aware that the device as herein illustrated and described issusceptible of alterations and modifications and of other uses than asan adjustable support for an incandescent lamp and it is not myintention that the appended claims shall be limited to the exactstructure or use illustrated.

I claim my invention:

l. In a device of the character described the combination with asupporting cord, of an adjuster therefor comprising an upper and a lowermember each of which is provided with a, direct and return channelthrough which the cord passes, means for supporting the upper memberindependently of the cord, said lower member being supported by the cordfrom said upper member.

2. In a device of the character described the combination wit-h asupporting cord, of an adjuster therefor comprising` an upper and alower member each of which is provided with a direct and ret-urn channelthrough which the cord passes, means for securing the cord'in the directchannel of the upper member, means for supporting said upper memberindependently of the cord, the lower member being supported by the cordfrom the upper member.

3. In a device of the character described the combination with asupporting cord and a fixed base to which it is attached, of an adjustertherefor comprising an upper and a lower member each of which isprovided with a direct and return channel through which the cord passes,means for gripping the cord in the direct channel of the upper member',devices having an arm located underneath said fixed part, and means forsupporting said upper member from said devices independently of thecord.

4t. In a device of the character described the combination with asupporting cord, of an adjuster therefor comprising upper and lowermembers each of which is made in two or more sections, direct and returnchannels formed in part in the sections of each member, and means forholding said sections together.

5. In a device of t-he character described the combination with asupporting` cord, of an adjuster therefor comprising an upper and alowermember each of which is provided with a direct and return channel, thecord entering the direct channel of the upper member and leaving thedirect channel of the lower member, the intermediate parts of the cordpassing through the return channel of both members, and means in thedirect channel of the upper member for engaging t-he cord.

6. In a device of the character described a depending supporting cordand an `adjuster therefor comprising upper and lower members, a directchannel in the upper member into which the cord is entered and meanstherein for gripping said cord, return channels in both members throughwhich the cord passes, and a direct channel in the lower member throughwhich the other end of the cord passes, the opening into the dire-ctchannel of the upper member and the outlet from the direct channel ofthe lower member being substantially in ali nement.
